Preparation of Aryloxetanes and Arylazetidines by Use of an Alkyl−Aryl Suzuki Coupling

The oxetan-3-yl and azetidin-3-yl substituents have previously been identified as privileged motifs within medicinal chemistry. An efficient approach to installing these two modules into aromatic systems, using a nickel-mediated alkyl-aryl Suzuki coupling, is presented.
